Description
Technical field
The invention belongs to field of ocean engineering, it is related to a kind of device for underwater pipeline laying.
Background technology
As the mankind deepen continuously to ocean development, become increasingly necessary in submarine laying transfer pipeline or circuit,
The pipeline or transmission of electricity or information transfer cable of oil gas are for example conveyed, for the safety for ensureing transmission of electricity or information transfer cable is generally also needed
In putting it into the pipeline of advance laying.
The laying method of current submerged pipeline is mainly：Ship is by laying-out is in place and positioning of casting anchor during pipe laying.It is prefabricated
Pipeline section aboard ship connect connect after from stinger enter water in, pipe laying barge progressively moves forward by mooring system, is soldered one section of advance
One section.This is lay method current at present.70 pipe laying barges are only there are about in the world by nineteen eighty-two, and the maximum pipe laying depth of water is reachable
200m, can spread the pipe of diameter 1120mm.
But, the mode that taking aboard ship carries out pipeline section connection not only needs the equipment such as stinger, and connects pipeline
Seabed is got to by pendency transition more long obliquely to seabed from ship, so ship will carry pendency transition
The weight of pipeline.This section of pendency section body not only increased the load of ship, and easily cause the damage of pipeline.Ship and pipe
Body interacts, and particularly when stormy waves is larger, the motion of ship acts on pipeline and is easily damaged pipeline, the motion of same pipeline
Act on ship and be also easily damaged ship, threaten the safety of ship.In addition, seabed is generally uneven, engineering is generally required
Ship carries out groove that is smooth or taking laying pipeline to seabed in advance, is again buried pipeline by working ship after laying pipeline, pole
Its trouble.
The content of the invention
The purpose of the present invention is directed to existing technology and there is above mentioned problem, it is proposed that a kind of underwater pipeline laying auxiliary dress
Put, this underwater pipeline laying servicing unit realizes the sectional pipe decentralization of pipeline, it is to avoid pendency section occurs in pipeline, reduces what ship was received
Pendency pipeline load, reduces the risk that pipeline and ship are damaged, and seabed is carried out while pipeline is laid smooth or dug
The groove of laying pipeline is taken, and is buried to laying pipeline.
The purpose of the present invention can be realized by following technical proposal：A kind of underwater pipeline laying servicing unit, including with
